Marine Spark Plug Wires

The function performed by spark plug wires is virtually the same in each gasoline motor, except for those relying on the coil-on-plug design and using ignition boots instead of wires. These flexible electrical conductors transfer high-voltage impulses to spark plugs, and their length, electrical resistance, and type of terminals are carefully selected depending on the engine make and model. When it comes to the ignition wires meant for marine use, their manufacturers typically pay more attention to quality isolation, corrosion resistance, and other factors caused by the environment.

The terminals of such wires are often made of stainless steel, copper, or bronze, while the cores usually feature a multilayer structure and can be reinforced with aramid fiber. Besides, there are various solutions aimed at enhanced isolation, such as the use of silicone impregnated fiberglass, EPDM, or other materials resistant to heat, abrasion, and chemicals. On our digital shelves, you will find a great variety of marine spark plug wires sourced from reputable brands such as CDI Electronics, Standard, PerTronix, and others. These companies implement cutting-edge technologies allowing you to enjoy the impeccable performance of your vessel's engine.
